Calulate the surface area of a cylinder with 20cm width and 20cm hieght

5026.55 cm^2

Step-by-step explanation:

Formula for calculation surface area of a cylinder : 2πrh+2πr^2

Width/radius = 20cm

Height = 20

Therefore:

2(3.14)(20)(20) + 2(3.14)(20)^2

2(3.14)(20)(20) + 2(3.14)(20)(20)

Surface area = 5026.55 cm^2

i would go with the first one
